I've been reading up a little on Porvenir. It is mainly an 'indicated' resource (400mt) of 0.35% copper and 0.14 g/t gold with about 100mt 'inferred' at 0.29% copper and 0.12 g/t. That is based on 18,636m of drilling, which is less than for Bushranger, so we may be pessimistic assuming our MRE will only be inferred.
The cut-off grade is 0.16%. When you consider that this is in a mountainous region of southern Ecuador that will need power, water, transport links, workers accommodations, etc., then either SOLG are very optimistic on infrastructure costs or a 0.15% cut-off for Bushranger is looking very conservative.
